Abstract
A personal care composition is provided which includes a diester quat and a polyhydroxy quaternary ammonium salt. Preferably the composition is a lotion or cream which exhibits a dragginess in topical application onto the skin.
Claims
exact text as granted — not AI-modified1 . A personal care composition comprising:
(i) from about 0.05 to about 10% by weight of a diester quat of the following structure (I):
wherein R 1 and R 2 are independently selected from branched or unbranched, saturated or unsaturated radicals having from 13 to 23 carbon atoms; R 3 and R 4 are independently selected from an alkyl radical having from 1 to 4 carbon atoms; Y is independently selected from saturated or unsaturated alkylene radicals having from 2 to 8 carbon atoms; and X is an organic or inorganic anion;
(ii) from about 0.05% to about 10% by weight of a friction enhancing agent which is a salt of structure AB,
wherein A is a cationic charged component of the salt AB,
B is an anionic charged component of the salt AB, and
A has at least one quaternized nitrogen atom, at least two hydroxyl groups and a molecular weight no higher than about 400; and
(iii) from about 1% to about 98% by weight of a cosmetically acceptable carrier.
2 . The composition according to claim 1 wherein the diester quat has the structure II:
wherein R is a 15 carbon radical.
3 . The composition according to claim 1 wherein the diester quat is a N,N-di(β-palmitoylethyl)-N,N-dimethylammonium salt.
4 . The composition according to claim 1 wherein the diester quat is present in an amount from 1 to 4% by weight of the composition.
5 . The composition according to claim 1 wherein the X anion is selected from the group consisting of halide, nitrate, acetate, sulfate, phosphate, tosylate, methosulfate and combinations thereof.
6 . The composition according to claim 1 wherein the X anion is chloride.
7 . The composition according to claim 1 wherein the friction enhancing agent is a dihydroxypropyl tri(C 1 -C 3 alkyl) ammonium salt.
8 . The composition according to claim 1 wherein the friction enhancing agent is dihydroxypropyltrimonium chloride.
9 . The composition according to claim 1 wherein the friction enhancing agent is present in an amount from about 0.1 to about 8% by weight of the composition.Cited by (0)
